摘要： A data processing apparatus and method are provided that use monitoring circuitry to control operating parameters of the data processing apparatus. The data processing apparatus has functional circuitry for performing data processing, the functional circuitry including error correction circuitry configured to detect errors in operation of the functional circuitry and to repair those errors in operation. Tuneable monitoring circuitry monitors a characteristic indicative of changes in signal propagation delay within the functional circuitry and produces a control signal dependent on the monitored characteristic. In a continuous tuning mode operation, the tuneable monitoring circuitry modifies the dependency between the monitored characteristic and the control signal in dependence upon certain characteristics of the errors detected by the error correction circuitry. An operating parameter controller is then arranged, in the continuous mode of operation, to control one or more performance controlling operating parameters of the data processing apparatus in dependence upon the control signal. This enables efficient and robust control of those operating parameters in response to changes in environmental conditions.

摘要： A data processing system 2 is used to perform processing operations to generate a result value. The processing circuitry which generates the result value has an error resistant portion 32 and an error prone portion 30. The probability of an error in operation of the error prone portion for a given set of operating parameters (clk, V) is greater than the probability of an error for that same set of operating parameters within the error resistant portion. Error detection circuitry 38 detects any errors arising in the error prone portion. Parameter control circuitry 40 responds to detected errors to adjust the set of operating parameters to maintain a non-zero error rate in the errors detected by the error detection circuitry. Errors within the one or more bits generated by the error prone portion are not corrected as the apparatus is tolerant to errors occurring within such bit values of the result value.

摘要： An integrated circuit including a plurality of sensors configured to sense variations in supply voltage levels at points within the integrated circuit is disclosed. The plurality of sensors are distributed across the integrated circuit and have transistor devices such that process variations in the transistor devices within the sensors are such that a sensing result will have a random voltage offset that has a predetermined probability of lying within a pre-defined voltage offset range. The integrated circuit is configured to transmit results from multiple ones of the plurality of sensors to processing circuitry such that the variations in the supply voltage levels can be determined with a voltage offset range that is reduced compared to the pre-defined voltage offset range.

摘要： An integrated circuit 114 includes processing pipeline circuitry 40 comprising a plurality of pipeline stages 44, 46, 48 separated by respective signal value storage circuitry 48, 50, 52. Timing detection circuitry 54, 56, 58 coupled to the processing pipeline circuitry serves to detect as timing violations any signal transitions arrive at the signal value storage circuits outside respective nominal timing windows. Error detection circuitry 66 triggers an error correcting response if the timing detection circuitry indicates a predetermined pattern comprising a plurality of timing violations spread over a plurality of clock cycles of a clock signal CK controlling the processing pipeline circuitry. The predetermined pattern may be two consecutive timing violations.
